You know all the times that men complain about women talking too much? Apparently there's a biological explanation for the reason why women are chattier than men. Scientists have discovered that women possess higher levels of a "language protein" in their brains, which could explain why females are so talkative.

Previous research has shown that women talk almost three times as much as men. In fact, an average woman notches up 20,000 words in a day, which is about 13,000 more than the average man. In addition, women generally speak more quickly and devote more brainpower to speaking. Yet before now, researchers haven't been able to biologically explain why this is the case.
